JAM_FindUser(3) JAM subroutine library JAM_FindUser(3) NAME JAM_FindUser - Find message to a user SYNOPSIS #include <jamlib/jam.h> int JAM_FindUser(s_JamBase* Base_PS, ulong UserCrc_I, ulong StartMsg_I, ulong* MsgNo_PI); DESCRIPTION Scans the message base looking for a message written to a specific user. Arguments Base_PS The message base to use UserCrc_I The CRC32 value for the searched name StartMsg_I The first message number to look at. This value is not the mes- sage's unique number, but rather the absolute position of the message in the message base. Message 0 therefore means the first message. MsgNo_PI A pointer to a variable where the message number for the found message will be stored. This number is the absolute message po- sition in the message base. Message 0 means the first message. RETURN VALUE 0 if successful JAM_IO_ERROR if an I/O error occured. See JAM_Errno(3) JAM_NO_USER if no message was found EXAMPLES uchar Name_AC[32]; int Result_I; ulong Crc_I; ulong Msg_I; strcpy(Name_AC, "Bjorn Stenberg"); Crc_I = JAM_Crc32(Name_AC, strlen(Name_AC)); Result_I = JAM_FindUser(Base_PS, Crc_I, 0, &Msg_I); switch (Result_I) { case JAM_NO_USER: printf("No message for me.\n"); break; case JAM_IO_ERROR: printf("IO error %d\n", JAM_Errno()); break; } AUTHOR This manual page was created by Sir Raorn <raorn@altlinux.ru>, based on original JAMlib documentation by Bjorn Stenberg <bjorn@haxx.nu> and Jo- han Billing <billing@df.lth.se>.
